Circadian Rhythm and Plant Genes Fuel-Up
(1) One of the routes, of the mechanisms of energy absorption, by which some archaegenes became and function as active energy packages, i.e. became living organisms:
(2) My elsewhere note on the Origin of Circadian Rhythm applies neatly in Plant Genes Fuel-Up, too. Both these processes fit in with comprehension that genes-genomes are living organisms.
(3) Genome observed "Oscillating" in coordination with circadian rhythm:
But circadian rhythm may be innate gene-genome characteristic, inborn/brought-about at the energetic conditions during the genesis of genes in the process of phasing from chemical olygomer to replicating life, to genes, to base life energy packages …..
Chapter I, G. Life's Drive and Purpose
"1. If one accepts, intuitively and logically, Pasteur's observation that all life must come from previously existing life, then the answer to "what makes a mono- and poly-cell life-form a Life" is the answer to "what makes some molecular associations in cells LIVES", and vice versa. It is the "lifehood" of genes that makes us and all other forms of life on Earth living organisms, and evolution has been the route of Life's ever more complexing progress since the first replication of the first gene."

It occurs to me that the point of the above post has not been duly obvious, i.e. that it has not clearly explained the source of Earth's organism's Circadian Rhythm.
I therefore wish to add this to the original post, the emphasis that for the archaic genes, parents of all Earth's Life, direct sunlight was the only source of energy. Hence circadian rhythm is most certainly an innate gene-genome characteristic.
Chicken Or Egg First?
A) NOTTINGHAM, England, May 26 2006 (UPI):
>>>British scientists and a farmer say they have solved the question
of what came first, the chicken or the egg, saying the egg
definitely was the original.
Evolutionary genetics Professor John Brookfield of the University of
Nottingham told The Independent the same DNA code of the chicken and
the egg it came from proves the egg was first.
He said a living organism, in this case a chicken, keeps the same
DNA structure as it did when an embryo in the egg, The Independent
reports, "Therefore, the first living thing that we could say
unequivocally was a member of the species would be this first egg,"
King's College London Professor David Papineau and Charles Bourns,
chairman of the Great British Chicken trade board, agreed. They said
the egg could be a mutant change from any other animal that then
produced the chicken but not the other way around.<<<
This subject's matter is simply and only semantics/definitions. For
the purpose of chicken-egg discussion the first egg that yielded a
narrowly defined new-species-chicken was the first member of this
defined species. However, in life-evolution the new egg is
definitely not the first "living thing" that represents the new
chicken species. It is the egg's genome, a living organism
consisting of a commune of interdependent genes who long ago lost
their individual once-upon-the-time pre-celling-era capability of
independent living (replication), that is the first living thing of the species.
And this genome came to be in the egg by way of …
>>> During DNA duplication its precursors with progressively narrowed
potential give rise to progeny that adopt one of two or more
divergent fates. The choice is influenced by intricate regulatory
networks acting at multiple levels. Early in the DNA duplication
course precursors show low-level activation of all progeny genetic
programs. Bias toward a given lineage comes from environmental
inputs that activate powerful positive- and negative- feedback
loops, which work in concert to impose selective gene expression
